Sounds like EMC is really covering all the bases for deduplication, Chuck. One note: I never heard the "3D" terminology before. Is this some new EMC insider jargon?

Chuck Hollis

Hi Stephen --

There are more bases to cover, we're not done yet ... !!!

I think there's a natural tendency to shorten concepts to acronyms in our industry.

Remember Y2K?

Bjorn Svenheld

Hi Chuck. Yahknow, I sure appreciate your words here with a flavor of education on the subject matter, and I enjoy reading your posts in general. However, in this case I must comment; I have little faith in the expertise portrayed by EMC on the whole regarding their accumulative 15 minutes spent in the dedupe space. I'm also fairly certain that flogging this well established market place with dominating players like Data Domain, NetApp, Sepaton, and others, with this new jargon "3D" will only serve to muddy the waters to end users. Perhaps that's not without plan. In any case, I found a SNIA vendor nuetral tutorial to be very beneficial in explaining to my ops staff what deduplication is about, and where it fits. Covers EMC technologies as well. Respectfully - Bjorn

Hi Bjorn --

I think SNIA does a great job on providing (relatively) vendor-neutral education, which is very important during the early phases of a new technology entering the market.

As far as the 3D terminology, it's nothing more than a convenience, as typing (or saying) data deduplication over and over and over again. No attempt to muddy the waters, just an attempt at shorthand.

I had assumed that everyone had started to use it, since I hear the phrase "3D" from customers pretty frequently now. I guess I was a bit early to pick up on it.

    I try and write something new 1-2 times per week; less if I'm travelling, more if I'm in the office. Hopefully you'll find the frequency about right!
